Duplicate Along Path Tangent Rotation

Recommended Posts

I'm trying to do something that should be simple, but I'm struggling to get the desired results. Basically I'm just trying to do a network that will duplicate a symbol along some control geometry, just like working with the built in Duplicate Along Path function. I have the basics working, but what I can't figure out is how to get the objects to to face the correct orientation of the path, which is normally controlled by the 'Tangent to Path" option. Is there an existing node that will do this for me that I'm missing, or what is the process for calculating Tangent at each point that I've divided the curve into?
